[0035] With the continuous development of science and technology, smart watches have become an indispensable part of people's lives. Among them, a very convenient function is to operate the car key through the smart watch. The communication components installed in the watch receive and transmit the frequency signal of the car system, so that the user can operate the car key function of the car system through the watch. However, existing smart watches usually place the communication components inside the watch. The communication components are easily interfered by the metal shell of the watch and the internal electronic components. Due to the high degree of interference of the communication components, the receiving and transmitting signal performance of the communication components is reduced, making it impossible for the watch to accurately identify the vehicle signal, which easily causes the failure of vehicle signal reception, and thus cannot meet the normal car key function requirements.

[0036] The utility model provides a head type automobile key, aiming to solve the technical problem of how to improve the signal transmission effect between the head type automobile key and the automobile.

[0037] In the embodiment of the present utility model, Figure 1 , Figure 2 and Figure 5 As shown, Figure 1 This is a structural schematic diagram of an embodiment of a head-type automobile key of the utility model; Figure 2 This is a structural exploded view of an embodiment of a head-type automobile key of the utility model; Figure 5 This is a structural exploded view of an embodiment of a metal outer frame in the utility model.

[0038] The watch head type automobile key includes: a shell, the shell has an installation cavity, the shell includes a middle frame assembly, the middle frame assembly includes a non-metallic inner frame 10 and a metal outer frame, the non-metallic inner frame 10 is arranged in a ring shape as a whole, the metal outer frame includes a first metal connecting part 21 and a second metal connecting part 22, the first metal connecting part 21 and the second metal connecting part 22 are connected to the outer wall surface of the non-metallic inner frame 10, the first metal connecting part 21 and the second metal connecting part 22 are used to respectively connect the two ends of the strap, and at least one completely disconnected communication port 23 is formed between the first metal connecting part 21 and the second metal connecting part 22; a communication element, the communication element is installed in the installation cavity, and the communication element is used to communicate with the elements outside the shell.

[0039] In this embodiment, the watch-type car key can be understood as loading the car control function of the car key into the smart watch, so that the user can control the car by wearing the smart watch on the wrist. The watch-type car key can only have the function of controlling the car, or it can also have other functions such as displaying time and information reminder.

[0040] The shell can provide a mounting cavity for the functional components of the watch head type car key to play a protective role. The middle frame assembly is a part of the shell, and the middle frame assembly is a composite middle frame, wherein the non-metallic inner frame 10 can surround the mounting cavity, and the specific material of the non-metallic inner frame 10 can be plastic, TPU or silicone. The metal outer frame can improve the structural strength of the connection between the shell and the watch strap to prevent the shell from being easily deformed or damaged at the connection of the watch strap.

[0041] The communication element is used to realize wireless communication with the car so that the user can control the car through the head-type car key; there are many forms of communication between the communication element and the vehicle system, such as wireless communication through Bluetooth, 3G network, 4G network or 5G network, etc., which are not limited here.

[0042] For example, the communication element can be part of the smart key system, the smart key system (PASSIVE KEYLESS ENTER), referred to as PKE, which uses RFID wireless radio frequency technology and vehicle identity coding recognition system, applies the development plan of miniaturized, low-power radio frequency antenna, integrates the remote control system and the keyless system, and uses the traditional vehicle circuit protection to achieve dual radio frequency system and dual anti-theft protection. In the PKE system, the car acts as a base station and the head-type car key acts as a transponder to achieve two-way communication. The communication elements include receiving antennas, microcontrollers, high-frequency transmitting circuits, low-frequency receiving circuits, and control switches.

[0043] Of course, the communication element can also be an element in ultra-wideband wireless carrier communication technology. Ultra-wideband (Ultra WideBand) is referred to as UWB, which uses new ultra-wideband wireless technology that is very different from traditional communication technology. It sends and receives extremely narrow pulses of nanoseconds or less to transmit data to the vehicle, has a bandwidth of 3.1 to 10.6GHz, and is not easily interfered by other signals. Through the interaction between the UWB of the head-type car key and the vehicle's UWB, the positioning algorithm characteristics can be used to identify the centimeter-level distance from the vehicle, and quickly respond easily, so that users wearing head-type car keys can automatically control the car without feeling.

[0044] The metal outer frame and the non-metal inner frame 10 can be connected by an injection molding process, or they can be processed and formed separately and then connected together, which is not limited here. The first metal connection part 21 and the second metal connection part 22 both extend along the circumference of the non-metal inner frame 10. The first metal connection part 21 and the second metal connection part 22 can be connected to each other or set separately; that is, the end of the first metal connection part 21 away from the communication port 23 and the end of the second metal connection part 22 away from the communication port 23 can be connected or disconnected, which is not limited here.

[0045] The non-metal inner frame 10 has basically no shielding interference effect on the communication signal between the communication element and the car. The communication port 23 allows the communication signal between the communication element and the car to enter and exit the housing without the metal outer frame, thereby preventing the metal outer frame from interfering with the signal transmission of the communication element. The number of the communication ports 23 can be one, two or more, and is not limited here.

[0046] The completely disconnected communication port 23 formed by the metal frame can provide a signal transmission channel for the communication signal between the communication element and an external element (such as the car's on-board system), so that the signal transmitted and / or received by the communication element can interact with the external vehicle or accessories through the signal transmission channel, thereby greatly improving the strength of signal transmission and ensuring that the head-type car key can correctly identify the vehicle signal to improve the control effect of the car.

[0047] Specifically, Figure 5 As shown, the number of the communication ports 23 is two, one of the communication ports 23 is formed between one end of the first metal connection part 21 and one end of the second metal connection part 22, and the other communication port 23 is formed between the other end of the first metal connection part 21 and the other end of the second metal connection part 22.

[0048] The first metal connection part 21 has a first end and a second end in the extension direction, the second metal connection part 22 has a third end and a fourth end in the extension direction, the first end is close to the third end, the second end is close to the fourth end, a first communication port 23 is formed between the first end and the third end, and a second communication port 23 is formed between the second end and the fourth end. By setting the number of the communication ports 23 to two, the positions on the metal frame that can be used for the communication signal of the communication element to enter and exit can be increased, so as to further improve the communication effect between the communication element and the car.

[0049] The extension dimensions of the first metal connection portion 21 and the second metal connection portion 22 may be the same or different, which is not limited here.

[0050] In practical applications, such as Figure 4 As shown, Figure 4 It is a projection diagram of an embodiment of the middle frame assembly in the utility model. The two communication ports 23 are located on opposite sides of the non-metallic inner frame 10, that is, the extension size of the first metal connection part 21 and the second metal connection part 22 is the same. The two ends of the watch strap are usually connected to the 12 o'clock position and the 6 o'clock position of the watch head type car key, so the two communication ports 23 are respectively located at the 3 o'clock position and the 9 o'clock position of the watch head type car key.

[0051] For example, Figure 3 and Figure 5 As shown, Figure 3It is a schematic diagram of the structure of an embodiment of the middle frame assembly in the utility model. The first metal connection part 21 is provided with a first fixing hole 211 on one side facing the non-metal inner frame 10, the non-metal inner frame 10 is provided with a first through hole 11 corresponding to the first fixing hole 211, and the first fixing hole 211 is connected to the first through hole 11 by a fastener; and / or, the second metal connection part 22 is provided with a second fixing hole on one side facing the non-metal inner frame 10, the non-metal inner frame 10 is provided with a second through hole corresponding to the second fixing hole, and the second fixing hole is connected to the second through hole by a fastener.

[0052] Taking the first metal connection part 21 as an example, the fastener can be inserted into the first through hole 11 from the installation cavity and then fixedly connected with the first fixing hole 211, that is, the head of the fastener is located in the installation cavity, so that the fastener can be hidden to improve the appearance integrity of the middle frame assembly. The first fixing hole 211 can be a screw hole, and the fastener can be a screw. The fastener and the first fixing hole 211 are threadedly matched, thereby simplifying the connection process between the first metal connection part 21 and the non-metal inner frame 10. The number of first fixing holes 211 can be one, or two or more. Multiple first fixing holes 211 are arranged at intervals along the length direction of the first metal connection part 21, and the number and position of the first through holes 11 correspond to the multiple first fixing holes 211 respectively. Each first through hole 11 is connected to each first fixing hole 211 by a fastener, so that the connection position of the first metal connection part 21 and the non-metal inner frame 10 can be increased to improve the connection stability.

[0053] The specific connection method between the second metal connection part 22 and the non-metal inner frame 10 may refer to the first metal connection part 21 .

[0054] Specifically, Figure 3 and Figure 5 As shown, the first metal connecting part 21 is provided with a first positioning hole 212 on a side facing the non-metal inner frame 10, and the outer wall surface of the non-metal inner frame 10 is provided with a first positioning protrusion 12, and the first positioning protrusion 12 cooperates with the first positioning hole 212; and / or, the second metal connecting part 22 is provided with a second positioning hole on a side facing the non-metal inner frame 10, and the outer wall surface of the non-metal inner frame 10 is provided with a second positioning protrusion, and the second positioning protrusion cooperates with the second positioning hole.

[0055] Taking the first metal connection part 21 as an example, the first positioning hole 212 cooperates with the first positioning protrusion 12 to realize the pre-fixation of the first metal connection part 21 and the non-metal inner frame 10, so that the first fixing hole 211 and the first through hole 11 can be accurately aligned in advance, so as to facilitate the user to assemble the fasteners, so as to improve the simplicity and convenience of the connection process between the first metal connection part 21 and the non-metal inner frame 10. The number of the first positioning holes 212 can be one, or two or more. The multiple first positioning holes 212 are arranged at intervals along the length direction of the first metal connection part 21, and the number and position of the first positioning protrusion 12 correspond to the multiple first positioning holes 212, so that the pre-fixed position of the non-metal inner frame 10 and the first metal connection part 21 can be increased to improve the positioning effect.

[0056] The specific positioning method of the second metal connection part 22 and the non-metal inner frame 10 may refer to the first metal connection part 21 .

[0057] In practical applications, such as Figure 3 As shown, the outer wall surface of the non-metallic inner frame 10 is provided with a first positioning groove 13, and the first metal connecting part 21 is partially installed in the first positioning groove 13; and / or, the outer wall surface of the non-metallic inner frame 10 is provided with a second positioning groove, and the second metal connecting part 22 is partially installed in the second positioning groove.

[0058] Taking the first metal connection part 21 as an example, the first metal connection part 21 is partially embedded in the first positioning groove 13, so that the groove wall of the first positioning groove 13 can limit the first metal connection part 21, preventing the first metal connection part 21 from being displaced on the outer wall of the non-metallic inner frame 10, thereby improving the position stability of the first metal connection part 21.

[0059] The specific positioning method of the second metal connection part 22 on the non-metal inner frame 10 may refer to the first metal connection part 21 .

[0060] Exemplarily, the housing further includes a display panel 40 and a bottom shell 50, which are respectively disposed at the top and bottom of the non-metallic inner frame 10, and the display panel 40, the bottom shell 50 and the non-metallic inner frame 10 enclose the installation cavity. The display panel 40 has a touch interface, which can display functional information such as time and the current state of the car, and can also allow users to touch and control the car key function.

[0061] The bottom case 50 may be connected to the non-metal inner frame 10 or to the metal outer frame.

[0062] Specifically, Figure 2As shown, a first supporting portion 51 is protruded at the peripheral edge of the bottom shell 50, the first supporting portion 51 protrudes from the outer wall surface of the non-metallic inner frame 10 and is located on the bottom side of the first metal connecting portion 21, and the bottom of the first metal connecting portion 21 is connected to the first supporting portion 51; and / or, a second supporting portion is protruded at the peripheral edge of the bottom shell 50, the second supporting portion protrudes from the outer wall surface of the non-metallic inner frame 10 and is located on the bottom side of the second metal connecting portion 22, and the bottom of the second metal connecting portion 22 is connected to the second supporting portion.

[0063] Taking the first metal connection part 21 as an example, the first support part 51 can support the first metal connection part 21. Since the first metal connection part 21 is fixed to the non-metal inner frame 10, the first support part 51 is connected to the first metal connection part 21, and the bottom shell 50 and the non-metal inner frame 10 can be indirectly fixedly connected. In this way, the connection relationship between the bottom shell 50, the non-metal inner frame 10 and the first metal connection part 21 can be made more compact to improve the overall structural stability of the shell. The first support part 51 and the first metal connection part 21 can be connected by fasteners to simplify the connection method.

[0064] The specific connection method between the second metal connection part 22 and the bottom shell 50 can refer to the first metal connection part 21. Connecting the bottom shell 50 to the first metal connection part 21 and the second metal connection part 22 instead of connecting to the non-metal inner frame 10 can effectively utilize the structural strength of the first metal connection part 21 and the second metal connection part 22, and prevent the non-metal inner frame 10 from being easily deformed or damaged due to excessive direct force.

[0065] For example, Figure 3 As shown, the first metal connecting part 21 is provided with two first mounting protrusions 213 on a side away from the non-metal inner frame 10, and the two first mounting protrusions 213 are used to connect the same end of the watch strap; and / or, the second metal connecting part 22 is provided with two second mounting protrusions on a side away from the non-metal inner frame 10, and the two second mounting protrusions are used to connect the other end of the watch strap.

[0066] Taking the first metal connection part 21 as an example, the two first mounting protrusions 213 have first axial holes on their facing sides, and the end of the strap is provided with a connecting shaft, and the two ends of the connecting shaft are respectively matched with the two axial holes to realize the rotatable connection between the strap and the two first mounting protrusions 213.

[0067] Specifically, the watch head type car key also includes a watch strap, and the two ends of the watch strap are detachably connected to the first metal connection part 21 and the second metal connection part 22 respectively. The watch strap can be worn by the user on the wrist to realize the wearing of the watch head type car key. The watch strap can be a one-piece type or a two-piece type, which is not limited here. The tightness of the watch strap can be adjusted to adapt to users with different wrist thicknesses. The watch strap can be made of leather, TPU or silicone, or it can be made of metal. In combination with the above-mentioned embodiment of the first mounting protrusion 213 and the second mounting protrusion, the watch strap can be rotatably connected to the first mounting protrusion 213 and the second mounting protrusion. The watch strap is detachably connected to the metal outer frame, so that when the user does not want to wear the watch head type car key, the watch head type car key can be directly carried in a bag or pocket after removing the watch strap to meet the different usage scenario requirements of the user.

[0068] The utility model also provides an automobile assembly, which includes an automobile and a head-type automobile key.
